Window member and manufacturing method thereof

Abstract

A window member according to an embodiment includes a cover window including a hole area; and a protective film disposed on a surface of the cover window and including an adhesive layer on a surface facing the cover window. The adhesive layer includes a cured portion overlapping the hole area and having no adhesiveness.

What is claimed is: 
     
         1 . A window member comprising:
 a cover window including a hole area; and   a protective film disposed on a surface of the cover window, wherein the protective film includes an adhesive layer on a surface facing the cover window, and   wherein the adhesive layer includes a cured portion, which overlaps the hole area and lacks adhesiveness.   
     
     
         2 . The window member of  claim 1 , wherein:
 the protective film further includes a base layer, and   the adhesive layer is between the base layer and the cover window.   
     
     
         3 . The window member of  claim 2 , wherein:
 a thickness of the adhesive layer is less than a thickness of the base layer.   
     
     
         4 . The window member of  claim 1 , wherein:
 the cured portion is an area having an adhesive force of 0 gram-force (gf).   
     
     
         5 . The window member of  claim 1 , wherein:
 an area of the cured portion is equal to or greater than an area of the hole area.   
     
     
         6 . The window member of  claim 1 , wherein:
 the adhesive layer includes at least one of an acrylic adhesive, a silicone adhesive, or a urethane adhesive.   
     
     
         7 . The window member of  claim 1 , wherein:
 the hole area includes an opening exposing the cover window and a light blocking layer surrounding the opening.   
     
     
         8 . The window member of  claim 7 , wherein:
 the light blocking layer is between the cover window and the adhesive layer.   
     
     
         9 . The window member of  claim 8 , wherein:
 the light blocking layer is in contact with the cured portion.   
     
     
         10 . The window member of  claim 8 , wherein:
 a distance between the cover window and the protective film in the hole area is determined by a thickness of the light blocking layer.   
     
     
         11 . A manufacturing method of a window member comprising:
 preparing a protective film having an adhesive layer formed on a surface thereof;   positioning a jig including a jig hole to face the protective film;   forming a cured portion corresponding to the jig hole in the adhesive layer by irradiating UV light through the jig hole; and   attaching the protective film to a surface of a cover window.   
     
     
         12 . The manufacturing method of the window member of  claim 11 , wherein:
 the cover window includes a hole area on the surface, and   the jig hole corresponds to a planar shape of the hole area.   
     
     
         13 . The manufacturing method of the window member of  claim 12 , wherein:
 the attaching of the protective film to the surface of the cover window includes   attaching the protective film to the surface of the cover window, wherein the cured portion of the protective film overlaps the hole area.   
     
     
         14 . The manufacturing method of the window member of  claim 12 , wherein:
 an area of the cured portion is equal to or greater than an area of the hole area.   
     
     
         15 . The manufacturing method of the window member of  claim 11 , wherein:
 the protective film further includes a base layer in contact with the adhesive layer, and   a thickness of the adhesive layer is less than a thickness of the base layer.   
     
     
         16 . The manufacturing method of the window member of  claim 11 , wherein:
 the cured portion is an area where an adhesive force is 0 gf.   
     
     
         17 . The manufacturing method of the window member of  claim 11 , wherein:
 the adhesive layer includes at least one of an acrylic adhesive, a silicone adhesive, or a urethane adhesive.   
     
     
         18 . The manufacturing method of the window member of  claim 12 , wherein:
 the cover window further includes a light blocking layer defining the hole area.   
     
     
         19 . The manufacturing method of the window member of  claim 18 , wherein:
 the light blocking layer is in contact with the cured portion.   
     
     
         20 . The manufacturing method of the window member of  claim 18 , wherein:
 a distance between the cover window and the protective film in the hole arca is determined by a thickness of the light blocking layer.
